Choke Channel Geometry for Large Debris and Backpressure Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional choke systems are inefficient, leading to increased manufacturing and operating costs due to oversized components, as they fail to recognize the criticality of dimensions 2 and 3 in accommodating larger debris while maintaining acceptable fluid dynamics.
Innovation Solution
The choke system is redesigned with specific dimensions for the input and seat channels, allowing larger debris passage without enlarging the intake dimension, and incorporates dynamic valve stem coupling, wear rings, and unidirectional seals to manage backpressure and prevent component damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional choke systems use oversized components to accommodate larger debris, then debris passage capability is improved, but manufacturing cost and operating cost increase
Solution Approach 1:
The choke system is divided into multiple functional channels: an input channel for fluid entry, a body channel for debris passage, and a seat channel for sealing. This segmentation allows each channel to be optimized for its specific function, enabling the body channel to accommodate larger debris while the input channel maintains a smaller, more cost-effective size.
Solution Approach 2:
The patent introduces a three-dimensional channel configuration where the body channel extends beyond the input channel boundaries. This dimensional expansion in the body channel allows larger debris to pass through without requiring the entire choke system to be oversized, thus reducing manufacturing costs while maintaining debris passage capability.
2Adaptability or versatility
If the intake dimension is enlarged to pass larger debris, then debris passage capability is improved, but fluid dynamics performance deteriorates
Solution Approach 1:
The choke system separates the debris passage function (body channel) from the fluid control function (input channel and seat channel). This allows the body channel to be enlarged for debris passage while the input channel maintains its optimized dimensions for fluid dynamics, resolving the contradiction between debris capacity and fluid performance.
Solution Approach 2:
Different channels are given different dimensional characteristics suited to their specific functions. The body channel has larger dimensions to accommodate debris, while the input channel maintains precise, smaller dimensions optimized for fluid flow characteristics. This local differentiation allows each channel to perform its function optimally without compromising the other.
3Ease of manufacture
If fixed choke design is used, then manufacturing cost is reduced, but adaptability to different production requirements deteriorates
Solution Approach 1:
The choke system incorporates an adjustable gate mechanism that can be positioned at different openings relative to the seat channel. This dynamic capability allows the choke to adapt to different production requirements by controlling fluid flow through the body channel, while the overall fixed structure maintains manufacturing simplicity.
Solution Approach 2:
The choke system combines multiple functions in a single device: the input channel for fluid entry, the body channel for debris passage and flow control, and the seat channel for sealing. This multi-functionality provides adaptability to different production requirements while maintaining a relatively simple fixed structure that is cost-effective to manufacture.

AI summary
Embodiments include a choke system that passes enlarged debris despite having a relatively small diameter for an input port of the choke system. Embodiments also include systems to prevent dislodging of a choke seat when backpressure is supplied to the choke system. Embodiments also include scaling systems to prevent fluid leaks around the choke seat of the choke system.
